Ticks and Crosses
Clean
Your own small facts, dealt as a logic-grid puzzle: type three or four short lists in matching order and the page deals clues that lead to exactly one answer by deduction alone, then you solve it on a tick-and-cross grid with hints, a printable sheet and exports; a metered run words the clues in a voice you pick and the page checks each one. Built on the SkillSafe skill @guia-matthieu/thought-based-reasoning.
